.SH NAME
std::uppercase,std::nouppercase \- std::uppercase,std::nouppercase

.SH Synopsis
   Defined in header <ios>
   std::ios_base& uppercase( std::ios_base& str );   \fB(1)\fP
   std::ios_base& nouppercase( std::ios_base& str ); \fB(2)\fP

   Enables the use of uppercase characters in floating-point and hexadecimal integer
   output. Has no effect on input.

   1) Enables the uppercase flag in the stream str as if by calling
   str.setf(std::ios_base::uppercase).
   2) Disables the uppercase flag in the stream str as if by calling
   str.unsetf(std::ios_base::uppercase).

   This is an I/O manipulator, it may be called with an expression such as out <<
   std::uppercase for any out of type std::basic_ostream or with an expression such as
   in >> std::uppercase for any in of type std::basic_istream.

.SH Parameters

   str - reference to I/O stream

.SH Return value

   str (reference to the stream after manipulation).

.SH Example


// Run this code

 #include <iostream>

 int main()
 {
     std::cout << std::hex << std::showbase
               << "0x2a with uppercase: " << std::uppercase << 0x2a << '\\n'
               << "0x2a with nouppercase: " << std::nouppercase << 0x2a << '\\n'
               << "1e-10 with uppercase: " << std::uppercase << 1e-10 << '\\n'
               << "1e-10 with nouppercase: " << std::nouppercase << 1e-10 << '\\n';
 }

.SH Output:

 0x2a with uppercase: 0X2A
 0x2a with nouppercase: 0x2a
 1e-10 with uppercase: 1E-10
 1e-10 with nouppercase: 1e-10
